Sur les caract\u00e9ristiques techniques de certains appareils, tel les t\u00e9l\u00e9m\u00e8tres<\/a> et niveaux laser<\/a>, prot\u00e9g\u00e9 contre l’eau et la poussi\u00e8re on voie souvent appara\u00eetre \u00ab\u00a0norme IP d’\u00e9tanch\u00e9it\u00e9 suivi de 2 chiffres\u00a0\u00bb, mais sait-on \u00e0 quoi correspond ces deux chiffres ? et comment conna\u00eetre les capacit\u00e9s d’\u00e9tanch\u00e9it\u00e9 de son appareil ?<\/p>\n

En fait, la protection IP selon la norme DIN EN 60529 se d\u00e9fini de la mani\u00e8re suivante :<\/p>\n

\"norme<\/p>\n

Le premier chiffre<\/strong> correspond \u00e0 la protection contre les particules solides.
\nLe deuxi\u00e8me chiffre<\/strong> \u00e0 la protection contre l’eau.<\/p>\n

Ce qu’il faut savoir :<\/strong> plus le chiffre est \u00e9l\u00e9v\u00e9, plus la protection est bonne.<\/p>\n

Protection contre les corps solides<\/h2>\n

Voici les caract\u00e9ristiques exactes du premier chiffre<\/p>\n

0 Aucune protection
\n1 Protection contre les corps solides de taille sup\u00e9rieure \u00e0 50 mm
\n2 Protection contre les corps solides de taille sup\u00e9rieure \u00e0 12 mm
\n3 Protection contre les corps solides de taille sup\u00e9rieure \u00e0 2,5 mm
\n4 Protection contre les corps solides de taille sup\u00e9rieure \u00e0 1 mm
\n5 Protection contre les d\u00e9p\u00f4ts de poussi\u00e8re
\n6 Protection contre la p\u00e9n\u00e9tration de poussi\u00e8re ~ \u00e9tanche ~<\/p>\n

Protection contre les liquides<\/h2>\n

Voici les caract\u00e9ristiques exactes du second chiffre<\/p>\n

0 Aucune protection
\n1 Protection contre les chutes verticales de gouttes d\u2019eau sur un appareil en position normale
\n2 Protection contre les gouttes d\u2019eau avec une inclinaison de 15\u00b0 maximum par rapport \u00e0 la position normale
\n3 Protection contre l\u2019eau en pluie si celle-ci ne fait pas un angle de plus de 60\u00b0 avec la verticale
\n4 Protection contre les \u00e9claboussements et les projections d\u2019eau
\n5 Protection contre les jets d\u2019eau \u00e0 la lance
\n6 Protection contre les paquets d\u2019eau, les vagues, les jets puissants
\n7 Protection contre l\u2019immersion temporaire
\n8 Protection contre l\u2019immersion prolong\u00e9e<\/p>\n

A noter qu’une protection IP 66 est excellente (\u00e0 moins de vouloir prendre des mesures sous-marine et de nettoyer son appareil \u00e9lectronique au lave vaisselle) et qu’une bonne protection commence \u00e0 partir de IP 44, pour ce qui est de la protection 1 et 2 pour les corps solides, autant dire qu’elle ne sert \u00e0 rien vous imaginez un corps solide de 5 ou 1 cm rentrer dans votre appareil !<\/p>\n

PS : Si votre appareil ne dispose d’aucune protection d’\u00e9tanch\u00e9it\u00e9, ne vous inqui\u00e9tez pas, vous trouverez toujours une brouette sur votre chantier \ud83d\ude42<\/p>\n
